A large piece of furniture is used to reinforce the main door of the House Chamber as congress members carry their gas masks while being evacuated due to rioters entering the U.S. Capitol in Washington, DC, on Wednesday, January 6, 2021. The rioters were stopped at that center door. A pro-Trump mob broke into the U.S. Capitol, causing destruction, an evacuation, and at least four deaths.
